UNITED STATES PATENT OFFICE.

JAMES B. SOHUMAN, OF COLUMBIA CITY, INDIA-NA, ASSIGNOR OF THREE- FOURTHSTO AUGUSTIN BOICE, OF INDIANAPOLIS, INDIANA.

PNEUMATIC STACKER.

SPECIFICATION forming part of Letters Patent No. 683,997, dated October8, 1901.

Application filed December 19, 1900, Serial No. (N0 modem To aZZ whom itmay concern.-

Be it known that I, JAMES B. SCHUMAN, a citizen of the United States,residing at O0- lumbia City, in the county of IVhitley and State ofIndiana, have invented a new and useful Pneumatic Stacker, of which thefollowing is a specification.

My invention relates to an improvement in means for introducing strawinto a pneumatic stacker-tube from a separator.

The accompanying drawings illustrate my invention.

Figure 1 is a longitudinal vertical section. Fig. 2 is a sectional plan.Fig. 3 is an enlarged vertical section of parts shown in Fig. 1.

In the drawings, 3 indicates a fan and fancasing of anydesired form, and4 indicates the discharge-tube leading therefrom. Formed through therear wall of tube 4 in front of fan 3 is anopening 5, through which thestraw is to be inserted. Mounted adjacent perforation 5 are two rollers6 and 7, which extend substantially the entire width of spout 4. Locatedabove rollers 6 and 7 is a roller 8, and extended over the three rollersis an endless belt 9. That portion of the belt 9 extending betweenroller. 8 and roller 6 is substantially vertical, while that portionextending between rollers 6 and 7 lies just within spout 4 and extendsparallel or substantially parallel with the axis thereof. This portionof the belt 9 is supported by a platform 10, which extends betweenrollers 6 and 7.

To the rear of belt 9 and at some distance therefrom I provide a roller11, upon the shaft of which is pivoted a frame 12, which carries at itsfree end a roller 13. Extended over I rollers 11. and 13 is an endlessbelt 14. Frame 12 is arranged to swing uponthe shaft of roller 11, andthe roller 13 thereof is normally but yieldingly maintained close toroller 6 by means of springs 15. Secured to frame 12 so as to moveadjacent the lower end of opening 5 is a shield 10, which operates tokeep closed that portion of opening 5 between roller 13 and fan 3.

In operation belts 9 and 14: are arranged immediately forward of theseparating means of a separator in such position that the strawtherefrom will be discharged into theV-shap ed hopper formed by the twobelts, and said fan 3 and in the direction of discharge through spout t.Springs 15 yield so as toregulate the size of opening between the tworollers 6 and 13, according to the amount of straw passingtherebetween.- As the straw enters or is forced through opening 5 intospout 4 the blast from the fan 3 turns the inserted ends upward and backagainst that portion of belt 9 within the spout. Said portion, however,is moving in the same line as the blast, so that it supports the strawand prevents the formation of any eddies immediately adjacent opening 5.By this means the inserted straw is maintained in the direction of theblast and prevented from being doubled upon itself, so as to choke thedischarge-spout.

I claim as my invention-- 1. In a pneumatic stacker, the combinationwith a fan, and discharge-spout leading therefrom, of a feed-beltleading into said spout in front of the fan, and means for driving thatportion of the belt lying within the spout in the direction of blast.

2. In a pneumatic stacker, the combination with a fan, anddischarge-spout leading therefrom, of a pair of feed-belts leading intosaid spout in front of the fan, and means for supporting the forwardbelt so as to cause that portion within the spout to move substantiallyparallel to the direction of the blast.

3. In a pneumatic stacker, the combination with a fan, and adischarge-spout having an opening leading into said spout in front ofthe fan, of a pair of rollers mounted adjacent said opening, a beltpassing around said rollers and having a portion thereof lying withinthe spout, means for moving said belt so as to drive said portion in thedirection of blast, a second belt mounted upon a swinging frame,adjacent the first belt, and yielding means for maintaining the' freeend of said frame adjacent one of said rollers;

4. In a pneumatic stacker, the combination with a fan, and adischarge-spout having an opening 5 leading into said spout in front ofsaid fan, of a pair of rollers 6 and 7 mounted adjacent said opening,aroller 8, abelt 9, passing around said three rollers and having thatportion between rollers G and 7 lying within said spout 4, a roller 11,a frame 12 pivotally mounted thereon, a roller 13 carried by the freeend of said frame, a belt passing around said rollers 11 and 13, meansfor yieldingly holding roller 13 adjacent roller 6, and a shield 16carried by frame 12 adjacent opening 5, substantially as and for thepurpose set forth.
